Submersion only happens when the upper sector has lotag 1 and its vertical
neighbor has lotag 2 (this can be useful to create non-submergible above-water
sectors). Currently, only the player is handled. On the implementation side,
the water handling code is split into P_Submerge() and P_Emerge() preparing the
"teleportation", and P_FinishWaterChange() for the finalization.

Currently, the only kinds of tint that can be applied simultaneously are
one "palfrom" per player, plus one loogie tint per player. Each palfrom
still overrides the preceding one. However, this is not a big problem IMO
since palfroms decrease at the same rate (loogie tint decreases at half the
speed). This change is especially good for the splitscreen mod, since now
the tints of the two players won't compete with each other. See the comment
in the source for some properties of the blending formula.

g_player[].frags[MAXPLAYERS] was changed from an array of int32_t to one of
uint8_t, but the clearing code

The idiv instruction also signals an FPE when the resulting *signed* quotient
overflows, so we simply use div instead.

to lock the player for a longer time than 127 game tics.

The tiles used are BIGHOLE (1141) and VIEWBORDER (3250). Ideally we'd draw the
console background using something specially-coded instead of rotatesprite if
it's fully black anyway.

happened because of the ydim vs. bytesperline discrepancy again.

If input is cleared before, it can become impossible to cancel the video
when decoding and displaying a frame takes longer than a frame.

The library was built with GCC 4.6.1 and configured like
./configure --disable-vp8-encoder --disable-multithread --disable-spatial-resampling
On the aforementioned AMD system, this reduces the mean time for decoding a frame
from 18.2 to 15.4 ms, so IMO it's worth the somewhat hefty addition of 430 Kb.

On an AMD Phenom II X4 system with generic memory modules, this brings down
the mean time for this conversion from 16.5 to 10.5 ms.

This changes a constant inside the panning calculation from 256 to 255 (making
e.g. panning 255 and 0 the same in the "San Andreas fault" sign in E1L5) and
uses the correct reference wall for the "do panning correction?" conditional.
Now, the problematic walls should look the same as in Polymost.

This makes the corrections conditional on where they appear in (under-, over-,
white or mask wall).

I'm willing to make this one concession to correctness in the name of backward-
compatibility. I think that one reason why this has never cause a crash is that
tiles in BUILD are allocated in Ken's big allocache buffer, so oob accesses were
dampened by that (though they hit uninitialized data).

The event is run after drawing the scene, but before the overlays. To
make a screenshot from a script, set DOSCRSHOT to non-zero. It will then
be scheduled to run once after the drawing but before the above-mentioned
event. The screenshots will be called mcapXXXX.{png,tga}.

The map iterator now has init/finish capability, making it possible to
write scripts that aggregate data over multiple map files. One such example
calculates some statistics, the other loads art metadata and looks for
red walls with non-pow2 ysize tiles.

Non-pow2 wall/mask drawing in classic introduced cases where walls are
drawn "incorrectly" because they were constructed with the old behavior
in mind. Polymer appears to "correct" for it partially, but doesn't cover
all cases. Specifically, now we have:
- E1L1 first inside secret room (5000, 50000): Polymer draws like Duke 1.5,
classic now draws with an offset.
- E3L2 near the vault (-20000, 25000): both classic and Polymer draw with
offsets compared to Duke 1.5, but they're different!
This means that more research is needed into what makes these two cases
diverge, even though both have the same root cause.
!!! Also, mappers should abstain from using non-power-of two textures on
walls until this issue is resolved in a satisfactory fashion !!!

This was introduced with r2771, which fixed e.g. AMC TC city_si's mirrors,
but instructed the base drawrooms inside yax_drawrooms to not correct the
passed sectnum. Therefore, stuff would get drawn wrongly when passing
sector boundaries, like from the platform to the rails in trueror1.map.

Related to that, it looks like out-of-bounds accesses when drawing such walls/
maskwalls or *sprites* are fixed, too. Sprites still show a stray lines on some
occasions, but Valgrind doesn't complain then.

Most notably, -Wdeclaration-after-statement. This and -Wpointer-arith
give some warning on linux, but this is "harmless" as it's assumed that
we'll be always compiling with GCC or Clang there.

-Wwrite-strings is useful to detect code where string literals and e.g. alloc'd
strings are used side-by-side, potentially creating dangerous situations, or to
find uses of old, non-constified APIs. However, enabling it would still flood
the log with too many warnings. Also, GCC wrongly warns for initializations of
char arrays.

Most differences are handled with function parameters, except that one instance
checked SpriteProjectile[i].spawns for being >0 instead of >=0. The factored
function always checks for >=0.

uhypsq calculates the hypotenuse using unsigned multiplication. This is
permissible since for arbitrary int32s a and b, the following holds in
two's complement arithmetic:
(int32_t)((uint32_t)a * b) == (int32_t)((int64_t)a * b)
("Signed and unsigned multiplication is the same on the bit level.")
This fixes various overflows where wall lengths for walls of length > 46340
are calculated, but does not rid us of other overflows in the same vein
(usually dot products between vectors where one point is a wall vertex and
the other a position in a sector).

The latter shows that "int32_t ksqrt(int32_t)" also copes with values in the
range INT32_MIN..-1, effectively interpreting them as uint32_t (i.e. adding
2**32). However, this should not be relied on from CON.

Arrays inside structs must not be accessible, since they're not bound-checked
by the FFI. Therefore, we flatten them into repeated scalar fields and need
to write accessor functions later.

That is, "clang -ftrapv" builds don't abort almost immediately after entering
a level.
There are various classes of overflow bugs, needing different handling:
- Some texture mapping code was written with signed integer wrapping semantics
in mind. In some places, we're able to get away with unsigned casts.
- sometimes, we really need a wider range, like when calculating distances or
dot products
- negating INT_MIN. Here, we cast to int64_t temporarily. Note that if the
result is 32-bit wide, no 64-bit code may actually need to be generated.
- shifting into a signed integer's sign bit. We cast to uint32 here.
- in hitscan(), at the "abyss crash prevention code" comment, it's clearly
the other code that is better...
This is not merely done for pedantry, but rather makes it easier to track down
overflow bugs having a real impact on the game.

For SDL 1.2 and when building on linux, the code using
clock_gettime(CLOCK_MONOTINIC, ...) is taken over from SDL HG.
gethitickms() is a convenience function that return milliseconds as
doubles and isn't exposed in any header file, yet.

Doesn't work: indexed-color modes, gamma (at least for X11), mouse wheel,
special keys like ENTER or BACKSPACE in the OSD, probably more...
In build/Makefile.shared, we now have logic to autodetect an SDL2 installed
in /usr/local, however OS X and Wii builds follow other Makefile code paths,
it seems. Note that the matching SDL2_mixer must be used then, too.
In source/jaudiolib/src/driver_sdl.c, change the #includes from <SDL/SDL_xxx.h>
to "SDL_xxx.h". SDL wiki says this is the most portable way, hopefully this
doesn't break builds for anyone.
